Abstract
Genome wide association studies (GWAS) have identified autoimmune disease-associated loci, a number of which are involved in numerous disease-associated pathways. However, much of the underlying genetic and pathophysiological mechanisms remain to be elucidated. Systemic lupus erythematosus (SLE) is a chronic, highly heterogeneous auto-immune disease, characterized by differences in autoantibody profile, serum cytokines and a multi-system involvement. This study presents the Epione application, an integrated bioinformatics web-toolkit, designed to assist medical experts and researchers in more accurately diagnosing SLE. The application aims to identify the most credible gene variants and single nucleotide polymorphisms (SNPs) associated with SLE susceptibility, by using patient's genomic data to aid the medical expert in SLE diagnosis. The application contains useful knowledge of >70,000 SLE-related publications that have been analyzed, using data mining and semantic techniques, towards extracting the SLE-related genes and the corresponding SNPs. Probable genes associated with the patient's genomic profile are visualized with several graphs, including chromosome ideograms, statistic bars and regulatory networks through data mining studies with relative publications, to obtain a representative number of the most credible candidate genes and biological pathways associated with the SLE. Furthermore, an evaluation study was performed on a patient diagnosed with SLE and is presented herein. Epione has also been expanded in family-related candidate patients to evaluate its predictive power. All the recognized gene variants that were previously considered to be associated with SLE were accurately identified in the output profile of the patient, and by comparing the results, novel findings have emerged. The Epione application may assist and facilitate in early stage diagnosis by using the patients' genomic profile to compare against the list of the most predictable candidate gene variants related to SLE. Its diagnosis-oriented output presents the user with a structured set of results on variant association, position in genome and links to specific bibliography and gene network associations. The overall aim of the present study was to provide a reliable tool for the most effective study of SLE. This novel and accessible webserver tool of SLE is available at http://geneticslab.aua.gr/epione/.

Abstract
Demetra Application is a holistic integrated and scalable bioinformatics web-based tool designed to assist medical experts and researchers in the process of diagnosing endometriosis. The application identifies the most prominent gene variants and single nucleotide polymorphisms (SNPs) causing endometriosis using the genomic data provided for the patient by a medical expert. The present study analyzed >28.000 endometriosis-related publications using data mining and semantic techniques aimed towards extracting the endometriosis-related genes and SNPs. The extracted knowledge was filtered, evaluated, annotated, classified, and stored in the Demetra Application Database (DAD). Moreover, an updated gene regulatory network with the genes implements in endometriosis was established. This was followed by the design and development of the Demetra Application, in which the generated datasets and results were included. The application was tested and presented herein with whole-exome sequencing data from seven related patients with endometriosis. Endometriosis-related SNPs and variants identified in genome-wide association studies (GWAS), whole-genome (WGS), whole-exome (WES), or targeted sequencing information were classified, annotated and analyzed in a consolidated patient profile with clinical significance information. Probable genes associated with the patient's genomic profile were visualized using several graphs, including chromosome ideograms, statistic bars and regulatory networks through data mining studies with relative publications, in an effort to obtain a representative number of the most credible candidate genes and biological pathways associated with endometriosis. An evaluation analysis was performed on seven patients from a three-generation family with endometriosis. All the recognized gene variants that were previously considered to be associated with endometriosis were properly identified in the output profile per patient, and by comparing the results, novel findings emerged. This novel and accessible webserver tool of endometriosis to assist medical experts in the clinical genomics and precision medicine procedure is available at http://geneticslab.aua.gr/.

Abstract
Endometriosis is a pathological condition extensively studied, but its pathogenesis is not completely understood, since its pathophysiology stems from a broad spectrum of environmental influences and genetic factors. Moreover, the nature of this condition is heterogeneous and includes different anatomical entities. Scientists actively pursue discovery of novel biomarkers in the hope of better identifying susceptible individuals in early stages of the disease. High-throughput technologies have substantially revolutionized medical research and, as a first step, the advent of genotyping arrays led to large-scale genome-wide association studies (GWAS) and enabled the assessment of global transcript levels, thus giving rise to integrative genetics. In this framework, comprehensive studies have been conducted at multiple biological levels by using the "omics" platforms, thus allowing to re-examine endometriosis at a greater degree of molecular resolution. -Omics technologies can detect and analyze hundreds of markers in the same experiment and their increasing use in the field of gynecology comes from an urgent need to find new diagnostic and therapeutic tools that improve the diagnosis of endometriosis and the efficacy of assisted reproductive techniques. Proteomics and metabolomics have been introduced recently into the every day methodology of researchers collaborating with gynecologists and, importantly, multi-omics approach is advantageous to gain insight of the total information that underlies endometriosis, compared to studies of any single -omics type. In this review, we expect to present multiple studies based on the high-throughput-omics technologies and to shed light in all considerable advantages that they may confer to a proper management of endometriosis.

Abstract
The purpose of the present study was two-fold: First to review the epidemiological aspects of the experience on the surgical outcomes via laparotomy or laparoscopy, as regards endometriosis from two different academic institutions and, second, to illustrate potential differences in two different geographical areas, New Haven (US) and Greece. This retrospective study included 1,200 patients (15–80 years of age) treated via laparotomy or laparoscopy, at two different institutions, for endometriosis, between 1990 and 2017. Data were collected and analyzed from medical and pathological reports. The statistical methods used included the Student's t-test and χ2 test, as well as the Mann-Whitney U test. A total of 600 women from Yale University and 600 women from Greece participated in this study. Endometrioma was confirmed in 359 (29.9%) cases. Women were compatible in terms of the site of endometriomas. Left-sided cysts were observed (P<0.001) significantly more often compared with right-sided cysts in both groups. The two groups of patients had similar rates of endometriosis stages. A statistically significant positive association (P<0.001) was found for the co-existence of benign gynecological tumors (apart from endometrioma), endometriosis-associated ovarian cancer and for post-menopausal endometriosis in women with endometriosis from Greece. Moreover, similar results were observed as regards endometriosis following in utero exposure to diethylstilbestrol (DES), non-Hodgkin's lymphoma, endometriosis-associated Lyme disease, human immuno-deficiency virus (HIV), melanoma and endometriosis in adolescents, between the two groups. To conclude, the two populations exhibited similar results as regards the surgical outcomes of endometriosis laparoscopic or open surgery. Endometriosis represents a multifactorial entity that depends on complex interactions of hormonal, genetic, immunological and environmental factors. Gynecologists should be aware that there is an association between endometriosis and cancerous diseases. It is thus suggested that the presence of comorbidities in women with endometriosis.

Abstract
The coexistence of endometrioma with dermoid cyst of the ovaries is an unusual entity, although they are both common and benign gynecological tumors. The present study aimed to investigate the association between ovarian dermoid cyst (teratoma) and endometrioma. We retrospectively, included 315 women with endometrioma and 172 with ovarian teratoma. Data were collected from medical and pathological reports from two different areas between 1995 and 2018. The mean age of cases with endometrioma was similar (35.8±7.2 years) to patients with ovarian teratoma (34.2±6.8 years). Considering the types of dermoid cysts, the observed proportion of mature type was 168/172 (98%), the immature type was 4/172 (2%) and struma ovarii was14/172 (8.1%) respectively. Endometrioma was significantly more frequent in the left ovary [174/266 (65.4%)] than in the right ovary [92/266 (34.6%)], P<0.001. By contrast, ovarian teratoma were predominant in the right ovary, 98/172 (60.6%), compared to the left side, 56/172 (32.5%), P<0.001. Regarding the size of the masses, we detected an inverse distribution between the two groups. Thirteen women were detected with ovarian teratoma and endometriosis, with 6 cases being in the same ovary. Our results indicate a left lateral predispostion of endometrioma and a right of ovarian teratoma and suggest that the pathogenesis between these conditions is different. The coexistence of endometriosis with dermoid cyst of the ovary, presents a challenge to the physicians and the investigators. Further research is required to establish the relationship between endometriosis and ovarian teratoma.

Abstract
Endometriosis is a complex gynecological disorder, affecting up to 10% of women of childbearing age, characterized by the presence of functional endometrial tissue at ectopic positions generally within the peritoneum. It is a heritable condition influenced by multiple genetic, epigenetic and environmental factors, with an overall heritability estimated at approximately 50%. The aim of the present study was to evaluate the association of rs1250248 and rs11674184 single nucleotide polymorphisms (SNPs), mapping to fibronectin 1 (FN1) and growth regulation by estrogen in breast cancer 1 (GREB1) genetic loci, respectively, with the risk of endometriosis. A total of 166 women with endometriosis (stages I–IV) who were hospitalized for the condition, diagnosed by laparoscopic intervention and histologically confirmed, and 168 normal controls were recruited and genotyped. Genotyping of the rs1250248 and rs11674184 SNPs was performed with TaqMan primer/probe sets. A significant association was detected with the A allele, as well as the AA and AG genotypes of rs1250248 (FN1) in patients with endometriosis, as well as in patients with stage I and II of the disease only. The rs11674184 SNP of the GREB1 gene was not found to be associated with an increased susceptibility to endometriosis either for all patients (stages I–IV) or for subgroups of stage I and II or III and IV of the disease only. Our results demonstrated a genetic association between the rs1250248 (FN1) SNP and endometriosis at both the genotypic and allelic level. However, although rs11674184 of GREB1 constitutes one of the most consistently associated SNPs with endometriosis in European ancestry populations, it was not found to be associated with endometriosis in this study.

Abstract
Introduction: We aimed to describe and review the epidemiological aspect of the disease pattern of a series of perimenopausal and postmenopausal women with a histology confirmation of endometriosis. Material and Methods: We retrospectively examined the clinical records of 184 perimenopausal and 46 postmenopausal women with endometriosis. Data were collected and analyzed from 1100 patients' charts with confirmed endometriosis and involved cases from two different geographical areas, New Haven (US) and Greece. The statistical methods included ײ and the Mann-Whitney U test. In the perimenopausal group (age 45⁻54 years), there were 184 patients (16.7%) and the postmenopausal group (55⁻80 years) had 46 (4.2%). The average age of diagnosis was (49 ± 2.3) and (61.2 ± 5.1), respectively (p < 0.01). Results: Advanced endometriosis was more aggressive in the perimenopausal group (p < 0.05); in the same group, we observed a higher left-sided predisposition of endometriosis in comparison with the right side (p < 0.01). Endometrioma was the most common gynecological condition among patients with perimenopausal endometriosis in relation to the postmenopausal group (p < 0.001). Additionally, we found uterine leiomyomata more prominent in the perimenopausal group (p < 0.05). In contrast, adenomyosis was found higher in postmenopausal patients (p < 0.05); further, 24 cases with dry eye we observed. Conclusions: Postmenopausal endometriosis is an important underestimated condition. Although the reported situation is not common, various clinicopathological characteristics were observed in both groups. Clinicians should be aware that there is a correlation between endometriosis and endometriosis-associated ovarian cancer in perimenopausal and postmenopausal age.

Abstract
Endometriosis is a pathological condition which has been extensively studied, since its pathophysiology stems from a broad spectrum of environmental influences and genetic factors. Familial studies aim at defining inheritance trends, while linkage analysis studies focus on the identification of genetic sites related to endometriosis susceptibility. Genetic association studies take into account candidate genes and single nucleotide polymorphisms, and hence target at unraveling the association between disease severity and genetic variation. The common goal of various types of studies is, through genetic mapping methods, the timely identification of therapeutic strategies for disease symptoms, including pelvic pain and infertility, as well as efficient counselling. While genome-wide association studies (GWAS) play a primary role in depicting genetic contributions to disease development, they entail a certain bias as regards the case-control nature of their design and the reproducibility of the results. Nevertheless, genetic-oriented studies and the implementation of the results through clinical tests, hold a considerable advantage in proper disease management. In this review article, we present information about gene-gene and gene-environment interactions involved in endometriosis and discuss the effectiveness of GWAS in identitying novel potential therapeutic targets in an attempt to develop novel therapeutic strategies for a better management and treatment of patients with endometriosis.

Abstract
Endometriosis is an enigmatic condition with an unknown etiology and a poorly understood pathogenesis. It is considered to appear from the interplay of many genetic and environmental factors, affecting up to 10% of women and represents a major cause of pain and infertility. The familial association of endometriosis, as demonstrated through monozygotic twin and family studies suggests a genetic contribution to the disease, with further case-control and genome-wide association studies (GWAS) detecting various endometriosis risk factors. In a recent study, we described a unique, three-generation family of Cretan origin (Greece) with 7 females with surgically confirmed endometriosis (grandmother, 3 daughters and 3 granddaughters). All the affected members of this family displayed a variety of clinical manifestations and complications. In the present study, to further analyze the genetic variants conferring the risk of developing endometriosis, whole exome sequencing (WES) was performed, using the AmpliSeq technology on the Ion Proton platform. An initial analysis of 64 variants that were detected across the 14 genes previously confirmed to be associated with endometriosis, did not identify any deleterious exonic variants in these genes. However, further analysis revealed 2 hemizygous deletions in the grandmother that segregate in several of her affected offspring. The first deletion was found in the UGT2B28 locus, spanning 7 informative sequence variants across at least 14 kb. The second deletion, located in USP17L2, spans 3 informative variants across at least 2 kb. On the whole, the findings of the presents study implicate 2 additional genes in the pathogenesis of endometriosis, apart from those already identified by GWAS.

Abstract
Endometriosis is an enigmatic condition with an unknown etiology and poorly understood pathogenesis and women with endometriosis represent a high-risk population group for a large category of chronic conditions. The study focused on a 67-year-old woman who presented with a 40-year history of familial endometriosis associated with various non-gynecological co-morbidities, thus representing a unique case from a cohort of 1,000 patients with endometriosis. Her family history included infertile members suffering from endometriosis. Thirteen non-gynecological co-morbidities were documented throughout the years, including five autoimmune diseases (i.e., systemic lupus erythematosus, ankylosing spondylitis, multiple sclerosis, bronchial asthma and Crohn's disease), urinary bladder diverticulum, osteoporosis, multinodular goiter, cardiovascular diseases, gastroesophageal reflux disease, malignant tumor of urinary bladder, Barrett's esophagus and bilateral cataract. In order to understand the potential role of gene mutations in the development of all those co-morbidities, whole exome sequencing was performed and the presence of various disease-associated, potentially causal missense variants, were observed. These findings are in accordance with the previously suggested common underlying etiologic pathway for some, but not all, autoimmune disorders. This unusual case provides novel insights demonstrating that endometriosis can coexist with various chronic autoimmune diseases and other conditions, including non-gynecological malignancies, which possibly share a common genetic cause, a fact that should be taken into consideration seriously by clinicians.

Abstract
The aim of the present review was to discuss a matter of concern in the clinical field of obstetrics/gynecology, namely the potency of in vitro fertilization (IVF) in the management of endometriosis-associated infertility. Endometriosis is a medical condition affecting one tenth of women in their fertile years, and accounts for up to 50% of infertile women. Thus, such high prevalence has established the necessity for investigating the effectiveness of available techniques in eradicating the disease and constraining infertility as well as the accompanying pain symptoms of endometriosis. The underlying mechanisms connecting endometriosis with low fecundity have been extensively studied, both in terms of genetic alterations and epigenetic events that contribute to the manifestation of an infertility phenotype in women with the disease. Several studies have dealt with the impact of IVF in pregnancy rates (PRs) on patients with endometriosis, particularly regarding women who wish to conceive. Results retrieved from studies and meta-analyses depict a diverse pattern of IVF success, underlining the involvement of individual parameters in the configuration of the final outcome. The ultimate decision on undergoing IVF treatment should be based on objective criteria and clinicians' experience, customized according to patients' individual needs.

Abstract
We retrospectively analyzed clinicopathological data in two different countries over the past years on the association between ovarian endometriosis and ovarian carcinoma. Medical and pathological reports were evaluated from 1,000 patients with endometriosis from two different geographical areas. The prevalence and women characteristics of cases were analyzed. Endometriosis-associated ovarian cancer was present in 20 (2%) cases, among the study subjects. The observed prevalence was 12 (60%) for endometrioid carcinoma, 4 (20%) for clear cell ovarian carcinoma, 2 (10%) for serous and 2 (10%) for mucinous adenocarcinoma. A higher proportion of endometrioid carcinoma cases were noted in comparison with other types (P<0.001). We found only 3/20 (15%) postmenopausal cases. In all cases, we reported advanced stage of endometriosis (stage III or IV). Left-sided endometrioid carcinoma were notably more common than right-sided ones (P<0.001). In the majority of cases, malignant transformation of endometriosis was observed in endometrioid carcinoma or clear cell carcinoma of the ovary. Further research is required to establish the relationship between endometriosis and ovarian cancer.

Abstract
Endometriosis is one of the most common gynecological diseases affecting up to 10% of the female population of childbearing age and a major cause of pain and infertility. It is influenced by multiple genetic, epigenetic and environmental factors. Interleukin-16 (IL-16) is a proinflammatory cytokine playing a pivotal role in many inflammatory and autoimmune diseases as well as in the pathogenesis of endometriosis. The aim of the present study was to evaluate the association of two IL-16 gene single nucleotide polymorphisms (SNPs), rs4072111 and rs11556218, with the risk of endometriosis in women from Greece as well as to gain insight about the structural consequences of these two exonic SNPs regarding development of the disease. A total of 159 women with endometriosis (stages I–IV) hospitalized for endometriosis, diagnosed by laparoscopic intervention and histologically confirmed, and 146 normal controls were recruited and genotyped. Subjects were genotyped using a polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) strategy. A significant association was detected regarding the GG and GT genotype as well as 'G' allele of rs11556218 in patients with endometriosis. The rs4072111 SNP of the IL-16 gene was not found to be associated with an increased susceptibility to endometriosis either for all patients (stages I–IV) or for stage III and IV of the disease only. Our results demonstrated that rs11556218 is associated with endometriosis in Greek women, probably by resulting in the aberrant expression of IL-16, as suggested by the bioinformatics analysis conducted on the SNP-derived protein sequences, which indicated a possible association between mutation and functional modification of Pro-IL-16.

Abstract
The purpose of this study was two-fold, first to investigate the association between endometriosis and the risk of benign gynecologic tumors and, secondly, to evaluate the distribution of endometrioma and ovarian cysts in women with endometriosis. The medical and pathological reports of 1,000 women with endometriosis were retrospectively reviewed. The incidence of ovarian cysts, uterine leiomyomas and adenomyosis, as well as the side of ovarian cysts were further compared. A total of 295 cases of endometriomas, 172 cases of adenomyosis, 173 cases of ovarian cysts and 89 cases of uterine leiomyomas were confirmed histologically in patients with endometriosis. Serous cysts represented the most frequent diagnosis (n=81, 8.1%) in women with ovarian cysts, followed by dermoid cysts (n=15, 1.2%). In women with unilateral endometriomas, the observed proportion of left-sided cysts was found in 65.6% (164 of 250), significantly higher compared with right-sided cysts (86 out of 250, 34.4%) (P<0.001). Moreover, patients with other ovarian cysts were recognized as left-sided in 60% (96 out of 160) of cases, significantly higher compared with right-sided cysts (64 out of 160, 40%) (P<0.01). On the whole, the current study indicates that endometriosis may be associated with an increased risk of benign gynecological tumors, such as ovarian cysts, adenomyosis and leiomyomas. The results of this study confirm a left lateral predisposition of endometriomas and ovarian cysts.

Abstract
Endometriosis is a benign gynecologic disorder, affecting up to 10% of women, characterized by the presence of functional endometrial tissue at ectopic positions generally within the peritoneum. It is a heritable condition influenced by multiple genetic and environmental factors, with an overall heritability estimated at approximately 50%. In this study, we investigated whether single nucleotide polymorphisms (SNPs) rs7521902, rs10859871 and rs11031006, mapping to WNT4, VEZT and FSHB genetic loci, respectively, are associated with risk for endometriosis in a Greek population. This study included 166 women with histologically confirmed endometriosis diagnosed through surgery and 150 normal controls. Genotyping of the rs7521902, rs10859871 and rs11031006 SNPs was performed with Taqman primer/probe sets. A significant association was detected with the AC genotype of rs7521902 (WNT4) in patients with stage III and IV disease only. Evidence for association with endometriosis was also found for the AC genotype of the rs10859871 of VEZT. Notably, a significant difference in the distribution of the AG genotype and the minor allele A of FSHB rs11031006 SNP was found between the endometriosis patients and controls. We found a genetic association between rs11031006 (FSHB) SNP and endometriosis. WNT4 and VEZT genes constitute the most consistently associated genes with endometriosis. In the present study, an association of rs7521902 (WNT4) and rs10859871 (VEZT) was confirmed in women with endometriosis at the genotypic but not the allelic level.

Abstract
The aim of this study was to investigate whether five single nucleotide polymorphisms (SNPs), associated with endometriosis, may confer new insight towards a genotype‑phenotype association with endometriosis. We studied a three-generation family with seven women who had endometriosis. Blood specimens were obtained from all the affected female family members. The entire family was genotyped for five SNPs mapped to WNT4, VEZT, FSHB and IL-16 genetic loci. We further evaluated the members of the family with endometriosis and described all obstetric and gynecological complications caused by the disease in these seven women. The five SNPs analyzed did not reveal any genotype-phenotype correlation with the disease. The members of the family with endometriosis showed a variety of clinical manifestations and complications. None of the five genetic markers examined correlated genotype with phenotype in the case of the Greek three-generation family examined. Therefore, we conclude that more gene polymorphisms must be investigated in the members of this family to gain insight regarding a genotype‑phenotype correlation in endometriosis and the potential development of a personalized care for the patients based on these data.

Abstract
OBJECTIVE(S) The purpose of the study was to review patients' characteristics and the location of extrapelvic endometriosis. STUDY DESIGN Out of 1000 women with endometriosis during a 20year period, we found 200 cases with extra pelvic endometriosis. Medical reports were evaluated and the diagnosis was confirmed on the pathological specimen. This study involved cases from two different geographical areas, New Haven and Crete. The age, parity, symptoms, previous surgeries, diagnostic modalities, histopathological evaluation and location of endometriotic implants found in other areas were recorded and analyzed from the patient's charts. MAIN OUTCOME MEASURE(S) Statistical methods included x2 and Mann-Whitney U test s measuring incidence of right-VS left sided endometriosis. RESULTS 200 patients with extrapelvic endometriosis and 800 patients with pelvic endometriosis were included in the study. The gastrointestinal tract represents the most common location of extrapelvic endometriosis with 104/200(52%) cases (p<0, 01), followed by the urinary system with70/200(35%) cases. We observed the Left-sided ureter being involved in 49/200(24, 5%) cases, significantly higher compare with the right-sided ureter 21/100(10, 5%) (p <0, 01). All women had similar characteristics involving age, weight, main complaints, age of menarche, endometriosis stages, gravid and family history of endometriosis. CONCLUSION(S) The gastrointestinal tract and the urinary system are the most common sites of the extrapelvic endometriosis, which was obvious in both countries. Moreover, we observed that there are no significant differences in demographic variants, menstrual and reproductive characteristics in women with extrapelvic and pelvic endometriosis.

Abstract
OBJECTIVE p53, MDM2, and p21Waf1 are oncoproteins that regulate the cell cycle. The purpose of this study was to examine the distribution of p53, MDM2, and p21Waf1 oncoprotein expression in endometriomas and in adenomyosis. METHODS Tissue samples from 25 women with pathologically confirmed endometriomas and 31 women with pathologically confirmed adenomyosis were analyzed. Expression of p53, MDM2, and p21Waf1 oncoproteins was assessed by immunohistochemical nuclear staining. RESULTS p53, MDM2, and p21Waf1 expression were detected in 20%, 60%, and 80% of endometrioma tissue samples, respectively. All endometrioma tissue samples expressing p53 also tested positive for both MDM2 and p21Waf1. MDM2 expression was significantly higher in the proliferative than in the secretory phase of the cycle. In contrast, all 31 adenomyosis tissue samples were negative for p53, MDM2, and p21Waf1 expression. CONCLUSION The expression of p53, MDM2, and p21Waf1 suggests a role for these oncoproteins in the regulation of endometrioma cell growth, but not in adenomyosis.

Abstract
OBJECTIVE To examine whether the levels of MCP-1, RANTES and MCP-3 in the peritoneal fluid correlate with endometriosis. STUDY DESIGN Patients with endometriosis were compared with controls. SETTING Department of Obstetrics, Gynecology and Reproductive Sciences, Yale University School of Medicine, New Haven, CT, USA. SUBJECTS This study involved 95 women of reproductive age who were undergoing laparoscopy for evaluation of infertility or for pelvic pain. They were divided into an endometriosis group (n=54) and a control group (n=41). INTERVENTIONS Peritoneal fluid samples were obtained and β-chemokines (MCP-1, RANTES and MCP-3) were measured using ELISA. STATISTICAL ANALYSIS Mean and median values were used to present values. Due to the non-normality of chemokines, a log transformation was applied. Differences were examined using independent samples t-test. One-way ANOVA and Tukey HSD multiple comparison post hoc tests were applied. A significance level at 0.05 was set. RESULTS The levels of MCP-1 are higher (p for log values=0.024) in the control group (mean=687.6, SD=467.7 pg/ml) than those of the endometriosis group (mean=570.4, SD=633.1 pg/ml). The same is true for the median values of MCP-1 (control median=568.5, endometriosis median=384.7 pg/ml). MCP-3 and RANTES do not differ significantly (MCP-3 p=0.787, RANTES p=0.153). The levels of MCP-1 in patients with stage II endometriosis are significantly lower in comparison with stage III (p=0.048) and stage IV (p=0.033) endometriosis. CONCLUSIONS A decrease in the concentrations of MCP-1 in stage I endometriosis has been observed, which is even larger in stage II, in contrast to stage III and stage IV endometriosis, which exhibit concentrations similar to the controls.

Abstract
BACKGROUND The mechanical stress that the human diaphragm is exposed to during mechanical ventilation affects a variety of processes, including signal transduction, gene expression, and angiogenesis. OBJECTIVES The study aim was to assess the change in the production of major angiogenic regulators [vascular endothelial growth factor (VEGF), fibroblast growth factor-2 (FGF2), and transforming growth factor beta 1 (TGFB1)] on the human diaphragm before and after contraction/relaxation cycles during mechanical ventilation. METHODS This observational study investigates the diaphragmatic mRNA expression of VEGF, FGF2, and TGFB1 in surgical patients receiving general anesthesia with controlled mechanical ventilation (CMV) with muscle relaxation (group A, n = 13), CMV without muscle relaxation (group B, n = 10), and pressure support of spontaneous breathing (group C, n = 9). Diaphragmatic samples were obtained from each patient at two time points: 30 min after the induction of anesthesia (t1) and 90 min after the first specimen collection (t2). RESULTS No significant changes in the mRNA expression of VEGF, FGF2, and TGFB1 were documented in groups A and C between time points t1 and t2. In contrast, in group B, the mRNA levels of the above angiogenic factors were increased in time point t2 compared to t1, a finding which was statistically significant (pVEGF = 0.003, pFGF2 = 0.028, pTGFB1 = 0.001). CONCLUSIONS These findings suggest that the molecular response of the human diaphragm before and after application of diverse modes of mechanical ventilation is different. Angiogenesis via the expression of VEGF, FGF2, and TGFB1 was only promoted in CMV without muscle relaxation, and this may have important clinical implications.

Abstract
Background The efficacy and safety of a single dose of ampicillin/sulbactam compared to a single dose of cefuroxime at cord clamp for prevention of post-cesarean infectious morbidity has not been assessed. Methods Women scheduled for cesarean delivery were randomized to receive a single dose of either 3 g of ampicillin-sulbactam or 1.5 g of cefuroxime intravenously, after umbilical cord clamping. An evaluation for development of postoperative infections and risk factor analysis was performed. Results One hundred and seventy-six patients (median age 28 yrs, IQR: 24-32) were enrolled in the study during the period July 2004 - July 2005. Eighty-five (48.3%) received cefuroxime prophylaxis and 91 (51.7%) ampicillin/sulbactam. Postoperative infection developed in 5 of 86 (5.9%) patients that received cefuroxime compared to 8 of 91 (8.8%) patients that received ampicillin/sulbactam (p = 0.6). In univariate analyses 6 or more vaginal examinations prior to the operation (p = 0.004), membrane rupture for more than 6 hours (p = 0.08) and blood loss greater than 500 ml (p = 0.018) were associated with developing a postoperative surgical site infection (SSI). In logistic regression having 6 or more vaginal examinations was the most significant risk factor for a postoperative SSI (OR 6.8, 95% CI: 1.4-33.4, p = 0.019). Regular prenatal follow-up was associated with a protective effect (OR 0.04, 95% CI: 0.005-0.36, p = 0.004). Conclusions Ampicillin/sulbactam was as safe and effective as cefuroxime when administered for the prevention of infections following cesarean delivery.

Abstract
Despite the extensive research, endometriosis remains an enigmatic disease as up to now there is no consensus regarding the exact underlying mechanisms which could explain its development and progress. A local environment enriched in estrogens, progesterone resistance, local inflammatory response and multiple other molecular alterations appear to be pivotal events in the establishment and development of ectopic tissue. In the light of the evidence produced by molecular pathology research, in vivo and in vitro studies, modifications in current treatment options are anticipated. Current management of endometriosis is based on pharmacologic treatment and surgical intervention. In particular, combined oral contraceptives, danazol, gonadotropin-releasing hormone (GnRH) analogues and progestins have been extensively used in clinical practice. Novel agents that will hopefully improve the therapeutic potential include aromatase inhibitors, immunomodulators, anti-inflammatory agents, steroids receptor modulators and GnRH antagonists. It is still early for enthusiasm as there is limited knowledge about their short- and long-term side effects, their optimal administration route, their selectivity towards their target genes and the duration of treatment. Although there is a continual report of novel findings, the application of them in clinical practice is a long-lasting procedure requiring longitudinal clinical trials so as to achieve a balance between efficacy and safety.

Abstract
PURPOSE Women with endometriosis have been reported to be at increased risk of developing non-Hodgkin's lymphoma (NHL). The purpose of this article was to investigate the familial risk of NHL in women with endometriosis. We report on 10 cases with endometriosis and positive family history of NHL. METHODS The medical records of 405 women with endometriosis and 200 without endometriosis were retrospectively analysed. All of the cases were diagnosed by laparoscopy. Ten cases of endometriosis having first-degree relatives with NHL are reported. RESULTS We found no case with endometriosis and NHL. In contrast, we found 10/405 (2.5%) women with endometriosis and first-degree relatives with NHL. Their mean age was 38.3 years (range 29-46). The main complaint was infertility. The mean age at onset of endometriosis was 32 years (range 22-43). The stages of endometriosis were: stage II (n=4), stage III (n=2) and stage IV (n=4). All of these patients had first-degree relatives with a history of NHL. Five had mothers with NHL, 5 had fathers and one had a sister. CONCLUSION These cases could suggest a link between a family history of NHL and subsequent development of endometriosis in the first-generation women. Moreover, there was no evidence of association between endometriosis and NHL.

Abstract
Headless or unucleated spermatozoa were evaluated in semen specimens of 52 fertile men in order to investigate the frequency and the percentage of this morphological abnormality and to estimate the probable correlation of the abnormality with other semen parameters, since there are no available data. The only sperm parameter which correlated with the number of headless spermatozoa was the number of micro round-headed spermatozoa (r= + 0.4432, P<0.001). It is concluded that the high frequency of headless or unucleated spermatozoa in the semen specimens of fertile men, albeit in low percentage, does not seem to have any biological significance. Moreover headless and round-headed spermatozoa could be the outcome of the same pathogenetic mechanism.

Abstract
BACKGROUND The aim of this investigation was twofold: first, to demonstrate an association between endometriosis, ABO blood groups and Rhesus factor and, second, to show potential correlation of ABO blood group and stages of endometriosis. METHODS Two hundred and thirty-one women with endometriosis and 166 infertile women without endometriosis were studied retrospectively at the Yale University Hospital. All the cases were diagnosed by laparoscopy and in all of them ABO blood groups and Rhesus factor were determined by standard techniques. Women with endometriosis were divided into two groups according to the stage: Group 1 included 124 cases with stages I and II, and Group 2, 107 women with stages III and IV. Statistical methods included chi(2) and odds ratios (95% CI). RESULTS The identified distribution of ABO and Rh blood groups in women with endometriosis differed significantly from that of the women without endometriosis [chi(2) = 26.27, (P < 0.001); chi(2) = 18.71, (P < 0.001), respectively]. The blood group A was more predominant in women with endometriosis, while blood group O was less predominant. The overall risk of women with endometriosis and A blood group was 2.89 (95%CI, 1.85-4.52). No significant difference was detected in ABO and Rh blood groups in women with endometriosis according to the severity of disease. CONCLUSION Women with endometriosis have a 2.9-fold increased risk in the A blood group distribution. The role of blood groups in the development of endometriosis remains to be determined.

Abstract
Age, BMI, lifestyle, menstrual status and obstetric history can modulate the endocrine system and, therefore, have been hypothesised to play a role in in-vitro fertilisation (IVF) outcome. We designed a retrospective study, set in a medical school hospital. We evaluated the medical files of 297 infertile women who underwent laparoscopy and consecutive IVF-ET treatment in the Yale IVF unit between 1996 and 2002. The study group consisted of 151 women who conceived after IVF-ET and the control group of 146 women who underwent 288 IVF-ET cycles without pregnancy. The main outcome measure was the impact of epidemiological factors on the IVF outcome. There was no association between IVF outcome and race, BMI, age at menarche, length of cycle, duration and amount of flow, menstrual symptoms, other medical problems, medical history of allergies, and family history of endometriosis and cancer. We found that the degree of smoking and alcohol use was not a factor when comparing women with and without pregnancy after IVF (34.5% vs 29.5%, and 33.7% vs 27%, respectively). The rate of duration of infertility tended to be lower in pregnant women (35.9+/-23.4 months) vs (42.3+/-30.2) non-pregnant women. As expected, we also confirmed the inverse association between the age of women and IVF outcome. Overall, body attributes, lifestyle, family history, menstrual and reproductive factors were not related to IVF-ET outcome.

Abstract
BACKGROUND There are conflicting data concerning endometriosis and spontaneous abortion (SAB). The aim of the present study was to evaluate if there was any association between endometriosis and SAB. Moreover, we investigated risk factors in women with endometriosis and SAB. METHODS The medical files of 457 married women with endometriosis and 200 infertile women without endometriosis were studied retrospectively. All cases were diagnosed by laparoscopy. Data concerning demographic variables and menstrual characteristics were recorded from 226 women with endometriosis, which were divided into two groups. Group 1 included 126 cases with endometriosis and SAB, and Group 2 comprised 100 parous women with endometriosis and without SAB. Statistical comparisons between groups were made using the chi(2) test and odds ratios (OR) and 95% confidence intervals (CI). RESULTS The proportion of SAB was significantly higher in women with endometriosis than in infertile women without endometriosis (126/457 (27.6%) vs. 36/200 (18.0% ); OR = 1.7, 95% CI 1.1 = 2.6; p = 0.01). The frequency of nulligravid women was significantly higher in women with endometriosis than in the control group (OR = 1.9, 95% CI 1.4 - 2.81; p = 0.001). Mean age, age at onset of endometriosis, race, height, weight, body mass index, medical history of allergies, and family histories of endometriosis and cancer were similar in women with endometriosis and SAB and in parous women with endometriosis but without SAB. Moreover, the two groups were similar in age at menarche, length of cycle, duration and amount of flow, and the severity of disease. The incidence of infertility was significantly higher in women with SAB (p < 0.001). CONCLUSION These data suggest but do not prove that the risk of SAB is increased in women with endometriosis. The epidemiological risk factors of endometriosis are not associated with an increase in the abortion rate.

Abstract
OBJECTIVE To report a case of endometriosis associated with massive ascites, pleural effusion, and extremely elevated Ca-125. DESIGN Case report. SETTING University hospital. PATIENT(S) A 46-year-old, white nulligravida with bilateral adnexal masses, Ca-125 of 3,504 U/mL, abdominal pain, ascites, and a pleural effusion. INTERVENTION(S) Chemotherapy followed by exploratory laparotomy for suspected ovarian cancer. MAIN OUTCOME MEASURE(S) Surgical findings and histopathology. RESULT(S) Intraoperative examination and histology ruled out malignancy but found stage IV endometriosis. CONCLUSION(S) In rare instances advanced endometriosis may be associated with ascites, pleural effusions, and large pelvic masses. For this reason endometriosis should be included in the differential diagnosis of reproductive-age women presenting with apparent ovarian malignancy.

Abstract
OBJECTIVE To provide a review of the pathogenesis of polycystic ovary syndrome. DESIGN Literature survey. RESULT(S) Three major pathophysiologic hypotheses have been proposed to explain the clinical findings of polycystic ovary syndrome (PCOS) related to three major laboratory findings: the LH hypothesis, the insulin hypothesis and the ovarian hypothesis. Although the presence of many small follicles with a high androgen to estrogen ratio was first thought to represent a high rate of follicular atresia in polycystic ovaries, recent studies have demonstrated that the granulosa cells are viable and able to respond to FSH stimulation with normal increases in estradiol production. Thus, a new hypothesis has arisen that FSH activity is somehow blocked at the ovarian level. CONCLUSION(S) PCOS is a syndrome involving defects in primary cellular control mechanisms that result in the expression of chronic anovulation and hyperandrogenism. In this syndrome, the relation between the various parameters is of particular interest. These relations constitute the cornerstone of the pathogenesis of PCOS. The fact that the pathogenesis of PCOS has not yet been clarified, despite the plethora of relative information, may be the result of a general way of thinking in the interpretation of several scientific data, and especially those that refer to biochemical phenomena. The use of the various models of the theory of chaos, that permits a concrete approach for the interpretation of data, may constitute an optional procedure for the future understanding of the association of different parameters and their disturbances in the pathogenesis of the polycystic ovary syndrome.

Abstract
A 42-year-old woman with Stage IA, grade 3 clear cell ovarian carcinoma arising within an endometrioma after multiple ovarian stimulation attempts was a unique case from a total of 900 patients who underwent laparoscopy for infertility and pelvic pain between 1996 and 2002 at Yale University. Her previous treatments included two laparoscopic cystectomies for left ovarian endometriomas and four cycles of IVF-ET that resulted in one miscarriage and two successful pregnancies. Although it has been suggested that controlled ovarian hyperstimulation may predispose to the development of ovarian cancer, more recent studies postulate a protective effect if fertility treatments ultimately result in successful pregnancy. Our unusual case serves as a reminder that clear cell adenocarcinoma may coexist with endometriosis, and that parity does not necessarily protect infertility patients against the development of ovarian cancer.

Abstract
OBJECTIVE Peritoneal fluid (PF) inflammatory factors may participate in the pathogenesis of endometriosis. The aim of this study was to investigate PF interleukin (IL)-18 levels in women with and without endometriosis. DESIGN Controlled clinical study. SETTING Women undergoing laparoscopy at a university hospital. PATIENT(S) Fifty women with previously untreated endometriosis, 8 women on GnRH agonists for endometriosis, and 18 control women with normal pelvic anatomy who were undergoing tubal ligation. INTERVENTION(S) Peritoneal fluid IL-18 levels as measured by ELISA. MAIN OUTCOME MEASURE(S) Peritoneal fluid IL-18 levels. RESULT(S) Peritoneal fluid IL-18 levels were significantly higher in women with previously untreated endometriosis (mean +/- SEM, 91.1 +/- 6.5 pg/mL) than in control women (59.4 +/- 2.0 pg/mL). Interestingly, women with superficial (100.0 +/- 10.2 pg/mL) and deep peritoneal implants (94.0 +/- 10.8 pg/mL) had significantly higher PF IL-18 levels than did women with endometriomas (57.8 +/- 1.8 pg/mL). Similarly, women with stage I-II endometriosis (97.3 +/- 8.0 pg/mL), but not women with stage III-IV endometriosis (74.9 +/- 9.9 pg/mL), had significantly higher PF IL-18 levels than did control women. Peritoneal fluid IL-18 levels were significantly higher in the luteal phase than in the follicular phase but did not discriminate between women with pelvic pain or infertility. CONCLUSION(S) Peritoneal fluid IL-18 is elevated in women with peritoneal, minimal- to mild-stage endometriosis.

Abstract
DESIGN We examined 16 men who had been subjected to unilateral orchiectomy owing to seminoma and to preventive radiotherapy, in order to investigate the morphologic abnormalities of the spermatozoa (headless and small-round-headedness) that may contribute to infertility. RESULTS The same morphologic abnormalities of the head and neck found in the semen samples of fertile men were also found in the semen samples of the patients, albeit in higher percentages; the morphologic abnormalities of the tail in the semen samples of the patients were similar to those of the fertile men, both qualitatively and quantitatively. CONCLUSION No specifically characteristic morphologic abnormalities of the spermatozoa were detected in men who were subjected to unilateral orchiectomy and to preventive radiotherapy in comparison with fertile men. The percentage rate of morphologic tail abnormalities is not affected by preventive radiotherapy.

Abstract
BACKGROUND Interleukin (IL)-15 is a novel cytokine with immunoregulatory and angiogenic properties. We compared IL-15 levels in the peritoneal fluid (PF) of women with and without endometriosis. METHODS PF samples were obtained from 55 women with endometriosis (23 with superficial peritoneal implants, 19 with deep endometriotic implants and 13 with ovarian endometriomas). Eighteen women with normal pelvic anatomy undergoing tubal sterilization served as controls. RESULTS PF IL-15 concentrations were increased in women with endometriosis (2.7 +/- 0.5 pg/ml) versus controls (2.1 +/- 0.3 pg/ml; P < 0.001). However, IL-15 levels were higher in women with superficial peritoneal implants (2.9 +/- 0.5 pg/ml) than women with deep endometriotic implants (2.6 +/- 0.4 pg/ml; P = 0.01) or ovarian endometriomas (2.2 +/- 0.4 pg/ml; P < 0.001). IL-15 was also higher in women with deep implants than in those with endometriomas (P < 0.05). PF IL-15 correlated inversely with both depth of invasion (r = -0.52) and the stage of endometriosis (r = -0.42). PF IL-15 levels demonstrated little variation during the menstrual cycle, and did not discriminate between women with infertility or pelvic pain. CONCLUSION PF IL-15 levels are increased in women with endometriosis. However, IL-15 levels are inversely correlated with the depth of invasion and disease stage, suggesting a possible role for this cytokine in the early pathogenesis of endometriosis.

Abstract
PROBLEM Pregnancy-associated plasma protein-A (PAPP-A) belongs to a group of glycoproteins isolated from extracts of human placenta. Healthy ovarian and uterine tissues are also known to express PAPP-A. We hypothesized that PAPP-A levels might also be elevated in the peritoneal fluid (PF) of women with endometriosis, and examined variations in PF PAPP-A during the menstrual cycle and with the severity of the disease. METHOD OF STUDY PF PAPP-A were measured in 60 women with endometriosis and 38 women without endometriosis using a high-sensitivity immunofluorometric assay. RESULTS We found that the mean level of PAPP-A was higher in PF from patients with endometriosis than controls (p = 0.003). Furthermore, significant correlation was found between the stages of endometriosis and the levels of PAPP-A in these patients (r = 0.39, p = 0.009). The concentrations of PAPP-A in PF were significantly higher in the secretory phase than the proliferative phase of the menstrual cycle in both women with and without endometriosis (p = 0.009 and P = 0.002, respectively). Finally, among the controls, women undergoing tubal ligation had significantly lower mean PF levels of PAPP-A than women with infertility or pelvic pain (p = 0.001). CONCLUSION We conclude that PF levels of PAPP-A vary during the menstrual cycle, and are highest in the secretory phase. We also find that PF PAPP-A levels are significantly increased in women with endometriosis, and that the degree of elevation corresponds to the extent of disease.

Abstract
PROBLEM The objective of this study was to evaluate the possible relevance of cytokines in seminal plasma (SP) of patients with accessory gland infection and oligoterato-asthenozoospermia. METHOD OF STUDY Semen samples were obtained by masturbation from 90 men and were examined for the presence of interleukin (IL)-2, IL-6, IL-8, IL-11 and soluble CD23 (sCD23) by enzyme-linked immunosorbent assay. Five groups were included: (1) fertile men (n = 20), (2) infertile men with varicocele and oligo-teratoasthenozoospermia (V-OTA, n = 20), (3) infertile men with genital infection and OTA (INF-OTA, n = 20), (4) infertile men with idiopathic testicular lesion and OTA (ITL-OTA, n = 20) and (5) infertile men with azoospermia (AZOO, n = 10). RESULTS We found that the mean level of IL-2 was higher in SP from infertile men compared with SP from fertile men (P < 0.05). Mean levels of IL-6, IL-8, IL-11 in SP of INF-OTA were higher than that of all other groups (P < 0.05, P < 0.05, P < 0.001, respectively). However, no significant differences could be detected between other groups. A significant increase was noted in sCD23 levels in SP from men with ITL-OTA compared with all other groups (P < 0.01). We have not observed any correlations between IL-2, IL-6, IL-8, IL-11 and sCD23 levels in SP and semen parameters. Spearman's correlation coefficient revealed that there was a significant association between IL-6, IL-8, IL-11 levels in men with INF-OTA. CONCLUSION The measurement of each cytokine separately in the SP of men with INF-OTA, in spite of the existing significant differences, does not have a diagnostic value in male infertility. However, a combined determination of IL-6, IL-8, IL-11 in the SP of men with genital infection and oligo-terato-asthenozoospermia may provide clinically useful information for the diagnosis of male accessory gland infection.

Abstract
OBJECTIVE To determine the Bcl-2 and Bax expressions in endometriotic and adenomyotic tissues. In addition, to evaluate the Bcl-2/Bax status during the menstrual cycle in these tissues. METHODS A total of 56 women were retrospectively recruited from a University hospital setting. A total of 25 had endometriosis and 31 adenomyosis. Tissue samples were collected during gynaecological surgery and confirmed by histology to have endometriosis or adenomyosis. Bcl-2 and Bax expressions were investigated on 56 formalin-fixed and paraffin-embedded tissue by immunohistochemical staining and electron microscopy. RESULTS The difference of Bcl-2-positive protein between endometriosis and adenomyosis was not significant. No significant difference was found between Bcl-2 expression and the proliferative and secretory phase of the cycle in women with endometriosis, but this comparison was highly significant (P<0.001) in women with adenomyosis. The difference of Bax-positive protein between endometriosis and adenomyosis was not significant. In addition, no significant differences were found between the various phases of the cycle. We have found a stronger inverse correlation between the expression of Bcl-2 and Bax in endometriosis than in adenomyosis. CONCLUSIONS Our results suggest that the pathogenesis of ovarian endometriosis may be different from that of adenomyosis and the persistence of Bcl-2 and Bax expressions during both phases of the cycle in ovarian endometriotic tissues may have important implications for the survival and proliferation of the ectopic endometrial tissue.

Abstract
OBJECTIVE To investigate the role of IL-6, IL-8, and IL-11 in the immune-regulatory mechanisms involved in the spontaneous abortion of the first trimester of pregnancy. STUDY DESIGN Plasma levels of IL-6, IL-8, and IL-11 were determined in 68 women who had a spontaneous abortion of unknown aetiology during the first trimester of pregnancy. They were compared with the corresponding levels of 73 age-matched pregnant women who had an uneventful pregnancy, and 52 age-matched non-pregnant women. All enrolled women presented without any severe disease, syndrome or recent infection. Cytokine levels were measured by a sensitive sandwich enzyme-linked immunoassay. RESULTS The women with spontaneous abortion had significantly decreased plasma levels of IL-6, IL-8 and IL-11 compared to those with normal pregnancies (P<0.05). The non-pregnant women had no detectable cytokine levels. CONCLUSIONS The reduced plasma levels of IL-6, IL-8 and IL-11 in women with spontaneous abortion may be related to the underlying aetiopathogenetic mechanisms, however, there is no sufficient evidence for their use as predictive markers of pregnancy outcome.

Abstract
Fetal trophoblasts can be found in maternal circulation from an early stage of pregnancy and thus provide a potential source of DNA for non-invasive prenatal diagnosis. We have developed a two-step method for trophoblast isolation between the 8th and 12th week of pregnancy. Blood was sampled from 14 women undergoing termination of pregnancy or spontaneous abortion. Immunomagnetic beads precoated with HLA class I and II, and with anti-cytokeratin-18 monoclonal antibodies, were used to remove CD8+ and other maternal cells, and to select for fetal trophoblasts, respectively. Microsatellite analysis was performed on DNA extracted from the isolated, maternal, paternal and placental cells after PCR amplification. Recovery of the trophoblasts was confirmed in 13/14 cases (93%) by the identification of an identical microsatellite pattern for fetal and placental cells. Further evidence was the presence of heterozygous alleles of both maternal and paternal origin. The correct prediction of gender in all five male fetuses was an additional confirmation of trophoblast recovery. We conclude that trophoblasts can be effectively isolated from maternal blood in the first trimester, and by using polymorphic microsatellite markers to confirm sample purity, this method has potential future application in prenatal diagnosis.

Abstract
The aim of this study was to investigate the efficacy of recombinant human erythropoietin (rHuEPO) combined with parenteral iron, in the treatment of moderate and severe iron deficiency anemia during pregnancy. Twenty-six pregnant women, who had been ineffectively treated with iron supplementation alone for at least 8 weeks, were enrolled. They met the following criteria for inclusion in the study: hemoglobin (Hb) concentration <8.5 g/dl, evidence of iron deficiency anemia, and absence of other pregnancy complications, or severe systemic diseases. The treatment protocol comprised of a combination therapy with 150 IU/kg rHuEPO subcutaneously three times per week and 100 mg parenteral iron daily, for a total period of 4 weeks. Nineteen out of 26 women (73%) showed a quick response, with Hb reaching normal levels within the first 2 weeks of treatment. They displayed an average of 3.17 g/dl increase in Hb concentration during the total period of therapy, with 3.0 g/dl increase within the first 2 weeks. In 5 women (19.2%) there was no significant increase in Hb levels, while in 2 women (7.6%) a further decline in Hb concentration was observed, that necessitated a blood transfusion. In conclusion, rHuEPO combined with parenteral iron is an effective treatment for moderate and severe iron deficiency anemia during pregnancy, with minimal adverse or side effects. It may serve as an alternative to blood transfusion, or in cases of resistant anemia that are not effectively treated by iron supplementation alone. However, further studies are needed to investigate the poor response observed in about 25% of treated patients.

Abstract
STUDY OBJECTIVE To determine the concentration of plasma carnitine (total, free, and acylcarnitine) during the delivery of uncomplicated pregnancies of adolescent women. To investigate the relationship between maternal and neonatal levels of carnitine and to compare these carnitine levels between pregnant and nonpregnant adolescents. DESIGN Samples of maternal and umbilical blood were taken at the time of delivery and examined for the determination of the carnitine-total, free, and acylcarnitine-concentration by the use of an enzymatic-radioisotope method. Twenty-two cases of uncomplicated adolescent pregnancies with a normal labor and without perinatal complications were examined. The plasma level of carnitine was also examined in 17 healthy nonpregnant adolescent women, which constituted the control group. RESULTS The concentrations of plasma carnitine in adolescent pregnancies at the time of delivery were calculated at 19.6 +/- 2.15 microMol/L (total), 12.62 +/- 1.31 microMol/L (free), and 6.98 +/- 1.55 microMol/L (acylcarnitine). The corresponding mean values in umbilical plasma were 30.31 +/- 2.06 microMol/L, 22.39 +/- 1.64 microMol/L, and 7.92 +/-.96 mucroMol/L. There is a statistically significant difference between the mean values in maternal and umbilical plasma (P <.0001 for total and free carnitine and P <.012 for acylcarnitine). The correlations between adolescent pregnant women and their infants as regards total, free, and acylcarnitine were 0.137, 0.018, and 0.33, respectively. Neither of these parameters was statistically significant. The corresponding mean values of carnitine in nonpregnant adolescent women were statistically significantly higher than in adolescent pregnant women (total carnitine: 41.61 +/- 3.09 microMol/L, free: 31.39 +/- 2.81 microMol/L, acylcarnitine: 10.22 +/- 1.88 microMol/L, P <.0001). CONCLUSIONS The concentration of plasma carnitine at the end of adolescent pregnancy is low compared to the levels of umbilical carnitine at birth and that found in nonpregnant adolescent women. It may not have an obvious impact on the utilization of fatty acids in an uncomplicated full-term pregnancy; however, it suggests the potential risk for neonatal fatty-acid oxidation in a preterm or complicated pregnancy.
